Think you chose wisely there mate. The Young's kits come with much clearer instructions. If I remember correctly they give a minimum time of three weeks in primary or advise a fg before bottling. I gave my IPA 4 weeks. I had one a couple of months back (brewed in July) and although the hops had faded it still tasted better than most bottled ipa you buy in shops. There's plenty of stuff on here on the IPA so don't hesitate to check.
